LX40 route overview: ZRH to LAX

LX40 distance and great-circle path

LX40 covers 9,535 km, or 5,925 miles. That makes it an ultra-long-haul flight, near the limit of what most twinjets can fly non-stop. Of the 255 routes we track, it ranks 75 by distance.

The plane leaves Zurich heading north-west. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the ZRH–LAX route appears on a tracker map.

Why LX40 block time differs from cruise time

The schedule allows 12.2 hours from gate to gate. That works out to about 784 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See how timing changes the trip in our red-eye flight guide.

Can the Boeing 777-300ER comfortably fly LX40?

Not really. It uses about 70% of the Boeing 777-300ER's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Boeing 777-300ER.

What to know about LX40

  • Time change: you land 9 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.
